CHAIR.

T 0 all whom it may concern:

Be it known that I, BERT A. RUcoLns, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Chairs, of which the following is a specification.

My invention relates to improvements in adjustable reclining chairs and its objects are: First, to provlde a means whereby the weight of the occupant may be so distributed and adjusted upon the seat and the back of the chair that the chair may be readily disposed to meet any desired position of the occupant, within certain limits, and with the least possible amount of friction. Second, to provide a chair of the kind named, with which the back and the seatmay be readily removed or replaced without the necessity of removing screws or any fixed portion of the supporting elements of the chair. Third, to eliminate all pivot points between the back and the body of the chair and so arrange the substituted elements as to greatly reduce the strain and to practically eliminate friction with the movements of the parts. Fourth, to provide a means whereby the back and the seat may be readily separated or reassembled, either before or after removing them from the body of the chair. I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a sectional elevation of a chair practically on the line a: as of Fig. 3. Fig.

2 is an enlarged. view of the lower part of the same with the chair back removed to show the manner of attaching the adjusting plate to the body of the chair. Fig. 8 is a back view of the lower part of the chair. Fig. 4 is a side and an edge view of the lower end of the side of the back, and Fig. 5 is an edge elevation of the adjusting plate.

Similar letters refer to similar parts throughout the several views.

A, B, B, B, J represent the several parts of the supporting body of the chair. The seat frame D is pivotally supported to the front post B by means of a bracket, as E, which is provided with an open slot 6 for the reception and support of the pivot pin (Z, which latter is securely attached to the side rail of the seat frame.

The lower end of the back of the chair is supported by passing the stud I through the Specification of Letters Patent. Application filed. December 27, 1910.

plate G, and passing it downward therein to the bottom of the slot formed by the walls of the said rim. The adjusting plate G is, 1n turn, supported by being securely attached to the side rail A of the chair body. There are, of course, two of these adjusting plates, one attached to each rail of the body, and also one of the studs I attached to each side piece, C C, of the back in position to properly engage said plates to support both sides of the back. The studs I may be simply plain studs securely attached to the side pieces C of the back, or they may be made as antifriction studs by placing small rollers upon supporting pins I, as indicated in Fig. 4:.

To support the back end of the seat I secure a thin plate, as F, to each side rail of the seat and form a hook, as f, at the free end in position to be readily passed over the studs f, which latter are securely attached to the sides G a short distance above the lower ends thereof, so that with the studs I resting at z in the plate G the back will assume the position indicated by the solid lines in Fig. 1, and may be made to assume any position between this and that indicated by the dotted lines in said figure, by pressing backward upon the back H sufficiently to draw the stud I upward toward and to the point indicated at 2'.

It will be readily seen that with this construction, all that is necessary to remove the hack and seat is to remove the hook f from the stud f, the stud (Z from the bracket E and the stud I from the rim G when the seat and the back will both be disconnected from the body of the chair and each, the seat and the back, from the other so that the chair may be readily packed for shipping, or stored; and to reassemble the chair it is only necessary to reengage the several studs, hooks, rims and brackets, as hereinbefore described.

What I claim as new, and desire to secure by Letters Patent of the United States, is:

1. In combination with the body, back and seat of a reclining chair, a bracket secured to each side of the front of the body, said brackets having slots and openings thereto for the reception of lugs, an adjusting plate secured to each side of the back of the body, said plate having a rim that forms a slot therein, said rim being opened on one side near the upper end of each plate, a back having lugs at each edge to engage said rim and 7 slot to support the lower end of the back, a

lug projecting outward from each edge of the back above the adjusting plate, a seat frame having pins at the front end to engage the brackets and support the front of the seat, and hooks at the back to engage the upper lugs on the back of the chair, the back and the seat so balanced that a slight shifting of the weight of the body of the occupant upon the back and the seat will cause the lugs to travel in the slot in the adjusting plate and will shift the back to the desired reclining position, substantially as and for the purpose set forth.

2. In combination with the body, back and seat of a reclining chair, a bracket secured to the inside surface of each side of the body, said brackets each having a slot with an opening thereto, for the reception of supporting pins on the seat, an adjusting plate secured to each side of the back of the body, a rim on each of said plates that forms an open slot therein, lugs projecting outward from the lower end of each edge of the back, said lugs consisting of pins having antifriction rollers thereon arranged to work freely in the slots in the adjusting plates, a lug projecting outward from each edge of the back above the adjusting plates, a seat having pins arranged to engage the slots in the brackets and hooks arranged to engage the upper lugs on the back, all arranged to secure the back and the seat into the body, and to render the same readily adjustable by shifting the weight of the body of the occupant slightly from the one to the other.

3. In chair construction, a body, a back and a seat, the back of the chair slidably connected at the lower end with the body and arranged to be readily removed therefrom, the seat pivotally connected with the front of the body and readily removable therefrom, and pivotally connected with the back above the connecting points of the back with the body, and readily removable therefrom, substantially as shown and described.
